Dan, Those results are close enough for me too. I will explore your post more later. I laid the curves length out flat as you did and my surfaces curve edge came out in the 20's. Way off.

Since yours came out so close, I will explore and digress to what you've done there.

Thanks for getting back to me.

By pointing out the difference in the Rhino edge and the original, really miniscule, I was just pointing out that it is not an exacting thing, from what I have read and tried to learn on it. Your results are great too. I was assuming since you laid your line straight as did I that your curve would be way off like mine. But NOOOoooo. Mucho gracias for the post!

Here's a script Michael put together that you can run while in any of the curve,arc or line commands that will show the length in realtime.


script: /* Show length of current curve being drawn */ try { moi.ui.commandUI.setInterval( 'var crvs = moi.geometryDatabase.getObjects().getCurves(); var len = 0.0; if ( crvs.length > 0 ) { len = crvs.item(crvs.length-1).getLength(); } if ( !window["_crvdistlabel"] ) { document.body.insertAdjacentHTML( "beforeEnd", "" ); } _crvdistlabel.innerText = len.toFixed(4);', 250 ); } catch(e) {}


Start any of the commands, like arc or freeform or line, and pick your first point. Then hit the script and a label displaying the length will appear in the active command window. I wanted to ask for this label to be an editable field (Click and change the value) like the other EditSize boxes and such, but it just didnt seem that prominent of a function. I can get it other way's. I would be the guy who puts 10,000 tools on the front end. :O
